question for smart parts

i have a question for smartparts i have the stock board in my eos and if i leave a battery in it for a few hours or so the batter is completley dead and this is not even using it now i was wondering can i send in just the board and all or do i have to send in the whole gun??? i absolutley love the gun though

well for one u should always have a extra battery. did u buy it online or did u get it from a local shop? if u did just go back to the shop tell them about it, they should either be able to fix it or send to smart parts and they should.
